I duno, I used to run long filters like that from Penzoil. Didn't have any issues. If you have a skid plate, maybe. But otherwise, it was just fine. THanks for the heads up! Glad we might have a good alternative after I run out of Tokyo Rokis!

Nice find, I've been wondering about Mazda filters for a while since they're made by Tokyo Roki. I still have a good stash of the black Subie filters, but I might give these a try once we run out. Hubby still gets one heck of a discount at his old workplace (Marin Mazda-Subaru), too...

I use the purolator pl14610 at times (instead of the pl14612), which is basically the same as the subaru version but longer like that mazda one, haven't had any issues. However with the longer filter, it will be the lowest point on the car (aside from maybe the downpipe). So if you offroad it may not be the best idea (and might not clear some skidplates).

-edit-

Turns out the PL14610 IS the filter spec'ed by purolator for the 09+ RX8, so there should be no issue using the mazda version! (its also listed for a lot of mazda/ford/infiniti/nissan/dsm/honda/acura etc cars). Looks like this tokyo roki mazda filter will be perfect as it does have the higher bypass pressure (the purolators have pretty high bypass pressure compared to most other aftermarket ones, but not quite as high as the subaru/mazda oem ones)

Just a note, its only the 09+ that have the bigger can and higher relief pressure, the pre09 filters are the same as the aftermarket subaru ones (ie 11-18psi, and short)

Has anybody used this 09+ rx8 filter yet N3R1-14-302? I just bought a case, so I hope they work?

I'll be dissecting some filters soon. I found some made in Japan filters that may be relabled Tokyo Roki-should be here soon. Anybody want to send me a black Subaru OEM filter to compare with the blue Subaru OEM, 3 different made in Japan/Malaysia filters coming, and the N3R1-14-302 RX8 filters? I'll take pics and check out the bypass spring pressure.
